Horrible service

Absolutely horrible service I received at PNA in mall of the south . Went in to buy pens and wanted to pay with cash instead of card and the cashier that was assisting me called in someone else to help as she didn’t take cash I waited . That someone came through and the system was giving them problems understandably I stood there while they were busy with the system and while they wanted to find someone else who could assist , eventually someone came and you’d assume I’d be the first person that they assist. NOPE not at all a white guy that was actually behind me was called to be assisted while I was still standing , no explanation nor professionalism what so ever horrible experience based on my skin colour. I even asked those ladies that logically I should be assisted first before someone that’s after me but I assume they would rather make me wait and not the guy that was actually after me after standing for minutes.
